"Suspension anchor for transporting concrete parts"

The innovation concerns a suspension anchor for transporting concrete parts, consisting of a flexible rope loop with a pressed-on bushing having an external thread, the can be screwed into a holding part to be concreted into the concrete part and from a holding part screwed onto the socket Grommet which expands on the inside towards the free end of the rope and which preferably also has a threaded hole having coaxially extending guide stub, which corresponds to a conformally designed recess in the holding part .

In an embodiment already proposed, it is a suspension anchor of the type described above is to secure the grommet screwed onto the cable socket in the latter eir.e for axially extending transversely screwable bearings ■; - ': ar. decorative screw that can be supported by the book is provided. Furthermore, both .randteile of the rope are in the threaded socket pressed in.

The task of the innovation is now to simplify the. Auf hanging anchor of the type described at the beginning, ιι, ίηβ another task

723208130.11.72

is primarily to improve the load-bearing capacity »

The solution to this task is characterized by innovation characterized in that the grommet penetrated by the rope from the end facing away from the free socket face to the Socket is screwed on and one with the facing socket face has corresponding support shoulder, preferably also only one end part of the rope in the Bushing is pressed in, while the other end part of the rope is deformed into a loop, and preferably also the The inside diameter of the grommet extends from the support shoulder to the free end part of the rope up to the grommet jacket is designed expanded, and that the outer diameter of the grommet by more than 1 1/2 times larger than the outer diameter of the holding part is.

These measures make the one previously required unnecessary Clamping screw. In addition, by pressing only one part of the rope end into the socket, a significantly more intensive one Connection between the rope and the socket than previously achieved «Also can go far through the stressed design of the grommet higher at right angles to the axial elongation of the bushing Tensile forces so far, without the risk of damage to the Concrete part and / or a loosening of the embedded in the concrete part l!, - i] fceteiles from the suspension anchor onto the concrete part be transmitted.

A preferred and inventive arrangement of the .in the holding part screwed-in suspension anchor int characterized

da ^ the spout into a pre-formed corresponding recess of the concrete part, which can be supported on this, engages and preferably furthermore at least approximately with the adjacent one Concrete part side is arranged flush "

An embodiment of the innovation is in the drawing and is described in more detail below.

Hs show:

Fig _o 1 a suspension anchor mounted in longitudinal section,

FIG _o 2 likewise in the direction of the line AB of Fig. 1 seen.

Here, a holding part 2 is permanently set in concrete in a concrete part "1. The latter consists of a round bar section made of steel, which has an axially running threaded hole 3 and a cross-hole 4- ₀ Through the latter, a reinforcing bar 5 of the concrete part 1 engages into the threaded hole 4 a socket 6 made of light metal with an external thread is detachably screwed in. The socket 6 is permanently pressed onto one end part of a wire rope 7, while the other end part of the rope 7 is deformed into a loop 8.

A.3 disc-shaped grommet 9 is attached to the lynx. For this purpose, the grommet 9 has an internally threaded bore corresponding to the thread of the socket and is different from that of the rope loop 8 facing the end face of the socket 6 is screwed onto the latter. Furthermore, the spout 9 has a molded, ring-shaped closed shoulder 1o, which supported on the adjacent socket face. Of this

Shoulder 1o, the spout 9 has an approximately funnel-shaped extension 11 on the inside, which extends to the jacket, on which, as shown in dash-dotted lines, with tensile forces occurring at an angle to the axial extent the rope 7 is supported.

A guide stub 12 is also integrally formed on the spout 9, which engages in the conformal recess 13 of the holding part 2, The outer diameter of the spout 9, which is essentially designed as a circular disk, is approximately twice as large as that Lu.chmesser of the holding part 2, furthermore the spout is in a concrete partial recess 14 and is supported on the ground this recess.
